Abstract: An improved apparatus and method are disclosed for winding into a spiral roll the positive (186) and negative (241) plates of small cylindrical batteries. The originally flat positive and negative pasted plates are conveyed through stations at which they are automatically wrapped with strips of separator material (24, 84).
